Definitions
- the invention relates to energy supply, in particular the emergency electrical supply, a safety-relevant, electrically operated braking or steering system in a motor vehicle.
- Known electric brake systems have an electrically operated and electronically controlled actuator for generating the braking forces on each wheel brake, which is supplied by a central control unit with target values for the braking forces and then regulates these target values automatically.

In the fuel cell takes place under the catalytic effect of the electrodes a redox reaction takes place in which hydrogen and Oxygen water is generated.
- Fuel and oxidant are stored in separate storage tanks - in the following also as a fuel tank or Oxidizer container designated - provided.
- the energy content of the fuel cell system depends directly of the available fuel and oxidant quantities from.
- the storage content of the storage container is therefore a direct one Measure of the removable electrical energy content of the system.
- the determination of the "state of charge” is reduced thus on the determination of the storage contents of the storage containers.
- a simple one is sufficient for liquid fuels Level determination, with gaseous fuels can Reliable pressure and temperature of the storage tank the memory contents are closed.
- the fuel cell should not be recharged if it should after being used, the storage containers will be discharged simply replaced with new ones or replenished. Consequently there is no need for an expensive loading device.
- a failure of the fuel cell system should be noticed immediately and not only when the on-board power supply is impaired.
- a monitoring device is provided which continuously next to the fill level of the storage tank also the functionality of the fuel cell itself checked, and without using fuel.
- An electric brake system 1 has four on the wheels of the Vehicle-mounted wheel brake devices 2.
- Any wheel brake device 2 consists of a wheel brake actuator 3 and one associated electronic control device 4.
- the actuators 3 are operated electrically and via the electronic Control devices 4 controlled.
- a pedal simulator 5 sets Movements of a brake pedal 6, d. H. the one exercised by the driver Force and / or the pedal travel into electrical signals, which are fed to a control unit 7.
- In the control unit 7 are setpoints for the Braking, especially for vehicle deceleration and braking torques to be applied are calculated.
- the one from the control unit 7 calculated setpoints are via a communication system 8, e.g. via bidirectional data lines or a Bus system, to the control devices 4 of the wheel brake devices 2 transferred.
- control devices send 4 via this communication system 8 feedback data, such as the actual values of the braking torques to the control unit 7.
- the operating energy for electrical energy consumers in the system with trouble-free operation of the brake system 1 taken from an electrical system 9 of the vehicle.
- a Distribution and safety circuit (VSS) 10 takes over the allocation of energy flows to the individual wheel brake devices 2 as well as a short-circuit protection and a Separation of the brake system 1 into two brake circuits.
- the distribution and safety circuit (VSS) 10 is provided by the control unit 7 controlled.
- a fuel cell system 11 is used as emergency energy supply intended. It consists of the actual fuel cell 12, containers 13 and 14 for fuel or oxidizing agent and a valve unit 15, which in the connecting lines between the containers 13 and 14 and the electrodes 16, 17 the fuel cell 12 is switched and has valves 18, 19, through which the fuel or oxidant supply is controlled to the fuel cell 12.
- the fuel cell 12 consists of two porous electrodes - cathode 16 and Anode 17 - and an ion-conductive electrolyte 20, the the two electrodes 16, 17 are electrically conductive with one another combines.
- the valve unit 15 is controlled electrically and is such that the valves 18, 19 when acted upon with an electrical voltage below one specified minimum permissible operating voltage of the safety-relevant Systems is open.
- valves 18, 19 When applied with an electrical voltage greater than or equal to that permissible minimum operating voltage of the safety-relevant System is, the valves 18, 19 are closed against it.
- the Valve unit 15 is directly from the electrical system 9 of the braking system 1 fed. The valve unit 15 will be used later 3 described in detail.
- the cathode 16 of the fuel cell is connected to the ground line of the brake system 1, the anode 17 is connected via a Vehicle electrical system connection 21 connected to the vehicle electrical system 9.
- Vehicle electrical system 9 and vehicle electrical system connection 21 are connected to Vehicle electrical system 9 and vehicle electrical system connection 21 .
- a regenerative protection 22 - in the simplest case a diode - provided that prevents that from the fuel cell system 11 energy in one defective electrical system 9 is fed back.
- a monitoring circuit 23 which of the Control unit 7 is controlled during the operation of the safety-relevant Continuous monitoring of the systems Fuel cell 12 and the contents of the container 13, 14 before.
- the fuel cell 12 itself is monitored by a conductivity measurement of the electrolyte 20. If intact Supply lines, proper electrodes 16, 17 and functional Electrolyte 20 must be the total conductance in one specified range of values. If you leave this area, so is on a fault in the fuel cell 12 or in the supply lines, an error message is triggered and the control unit 7 brings the error to the driver, z. B. by activating a warning lamp, for display.
- the operating voltage for the valve unit drops 15 below the permissible minimum operating voltage of the safety-relevant System.
- the valves 18, 19 then return back to their rest position and the feed lines from the containers 13, 14 to the electrodes 16, 17 of the fuel cell 12 are released. This gets fuel and Oxidizing agent to the associated electrodes 17 and 16, a chemical redox reaction in which hydrogen and Oxygen water is generated, sets in and gives electrical Free energy for the operation of the brake system 1.
- the valve unit 15 remains de-energized and thus the valves 18, 19 opened further. to Bridging the switching process are in the distribution and Safety circuit 10 capacitive short-term memory, not shown (Capacitors) are provided.
- FIG. 2 shows an electric steering system 1 'as a further example for a safety-relevant system in a motor vehicle.
- A is shown Steering system with steered front wheels.
- Each steering device 24 consists of a Steering actuator 25, by which the steering forces are generated, and an electronic control device 26.
- sensors for example for steering angle and steering torque, on the steering wheel 27 of the vehicle, the driver's request is recorded. Based the sensor signals are then transmitted from a control unit 28 Setpoints for the steering forces generated.
- the rest of the system in particular the fuel cell system 11 corresponds to the system according to Fig. 1.
- Supply lines are thick in Figures 1 and 2, signal lines thin and communication channels as thin double lines located.
- valve unit 15 To control the fuel and oxidant supply serves the valve unit 15 with valves 18 and 19, which at Applying a voltage below the allowable Minimum operating voltage of the safety-relevant system is open, in particular in the de-energized state and when excited with a higher voltage conclude.
- Piezoelectrically operated valves are advantageous According to the principle shown in Fig. 3, the one valve unit 15 shows in the de-energized state.
- a valve block 30 receives valve pins 31 and a piezo element 32.
- the Piezo element 32 is preferably constructed in a stacked construction, so that it is with the usual low voltages in the vehicle can be operated. It consists of several geometrical serially arranged, but electrically connected in parallel Individual piezoelectric elements.
- valve seat elements are also in the valve block 30 33 introduced that the valve opening and Sealing surfaces for the valve pins 31 included.
- the valve pins 31 are lifted from the seats by springs 34. whereby in the de-energized state inlet and outlet channels for the fuel and oxidizer are open. at Applying a voltage to the piezo element 32 expands it out.
- the Valve pins 31 are then pressed down against the spring force and close the flow channels.
- the piezo element 32 and the springs 34 are preferably designed so that the inlet and outlet channels for the fuel and the oxidizing agent are only completely closed when on the piezo element there is a voltage greater than or equal to that permissible minimum operating voltage of the safety-relevant System is.
- valve unit 15 As an alternative to the described embodiment of the valve unit 15, it is also possible for each of the valves 18 and 19 for the fuel or oxidant supply via its own Control piezo element 32. Is atmospheric oxygen considered If the oxidizing agent is used, the valve unit 15 only the fuel valve 18 on. How it works remains basically unchanged.
- valves For use in emergency care for safety-related Systems with fuel cells offer such valves considerable Benefits. Because the piezo elements of the valves directly on the on-board power supply of the safety-relevant system is connected the valves are in normal operation, i.e. at functioning electrical system always in the closed state, d. H. the fuel cell becomes no fuel - and possibly Oxidizing agent - supplied. The fuel cell is therefore not in operation and there is no stored energy taken. Is the on-board power supply impaired, so that the vehicle electrical system voltage below the permissible minimum operating voltage of the safety-relevant system falls, so the open Valves automatically, the fuel cell goes into operation and gives electrical energy for the safety-relevant system free. In this way, the electrical energy consumers in the system at least partially from the fuel cell system provided.
- the electrical system is deliberately taken out of operation, e.g. B. by Disconnecting the vehicle battery for maintenance purposes can result in a Commissioning of the fuel cell system and thus consumption of fuel and possibly oxidizing agent be prevented that the storage container, advantageous via existing connection valves on such Containers. There is no partition for this the container from the supply lines to the fuel cell is necessary.
- Piezo elements consume in the steady state but almost no electrical energy - They correspond to a charged capacitor. at best dielectric losses and leakage losses due to the low Conductivity of the piezo material occurs. However, they lie many powers of ten under the self-discharge of a vehicle battery, thus affect the discharge of the vehicle battery de facto not.

Description
Der Verzögerungswunsch des Fahrers wird über Sensoren an einem Pedalsimulator erfaßt. Der Fahrer selbst hat keine Möglichkeit mehr, Bremskräfte über seine Muskelkraft aufzubringen (DE 196 15 186 C1). Weiterhin ist auch ein Einsatz elektrischer Lenkungen bekannt, bei denen sich an allen Rädern oder zumindest an der Vorderachse Stelleinrichtungen für den Lenkeinschlag der Räder befinden. Über Sensoren am Lenkrad wird der vom Fahrer kommende Lenkbefehl erfaßt. In einer Steuereinheit werden daraus Sollwerte für die Stelleinrichtungen ermittelt, die diese dann selbsttätig einstellen. Auch hier hat der Fahrer keine Möglichkeit mehr, direkt auf die Räder oder Lenkeinrichtungen einzuwirken.
